(Not sure if this should go here or in the Phone Booth, so feel free to correct me!)

I'm currently working on making some sprites for a (distant-)future Teen Titans fan-game, and I'm having trouble getting Robin's cape to flutter properly when he walks. This is my full image file thus far:https://imgur.com/5Xzg2F1

From someone that doesn't animate anything complicated, it looks to me like the sides of his cape kind of....spike downwards, if that makes sense? Like, when running in real life, it kind of flutters and flows behind, but the animation it looks more like it's jumping...like the fabric has a mind of it's own. It might be the shape, your eye really just sees the points (corners) moving downwards. I don't know if that's helpful, and I don't know what I'm looking at in the first file to actually help you improve it. The rest of the movements go really well together, I'm sure it's just a small tweak somewhere (hopefully!) and you'll get it just right! Good luck!!
